Product Detail



• All-in-One Design
Seamless integration of image sensor and decoder board makes the scan engine small, lightweight and easy to fit into even the most space-constrained equipment. (Seamlessly compatible with ES20)

• Snappy On-screen Barcode Capture
This scanner is capable of reading 1D and 2D QR code on a screen covered with protective film.

• HD Camera Module
CMOS camera module, high-precision bar code reading (3MIL), to easily identify all the mainstream 1d and 2d barcodes in the market. Paper, printing, plastic, mobile phone screen can easily read.

• Working Modes
Support a variety of working modes (manual, continuous mode, induction, command control), can meet the different reading requirements.

• OEM Development
Support for online upgrades, custom development, and secondary development.

Housing Design

※Note: Conduct an optical analysis for the housing design to ensure optimal scanning and imaging performance.
Housing design should make sure that internal reflections from the aiming and illumination system are not directed back to the engine. The reflections from the housing or window can cause problems. Avoid any highly reflective objects around the engine that can cause bright spots to appear in the captured image. It is recommended to use baffles or matte-finished dark internal housing colors.
